How to adjust the printing ink in the color printing process? The following will be introduced by printers in China:

Master the change law of the three primary colors in order to achieve accurate ink blending

We know that any color can be mixed and adjusted by using the different proportions of the three primary colors, and the hue of the ink changes by using this law. For example, the three primary color inks can become black (approximately) after being mixed and blended in equal amounts. The three primary color inks are mixed in equal amounts and added with different proportions of white ink to form a variety of light gray inks with different tones.

If the three primary color inks are mixed in various proportions, they can be mixed into a variety of inter-colors or multiple colors of different hues, but the hue is biased toward the primary color with a large proportion. If the two primary color inks are mixed in equal amounts, they can become standard secondary colors; after the two primary color inks are mixed and mixed in different proportions, they can be mixed into a variety of secondary colors with different hues, but their hue tends to be the primary color with a large proportion. In addition, in any color ink, the hue appears brighter after adding white ink. On the contrary, after adding black ink, its hue becomes darker. The above-mentioned blending of primary color inks into various colors is based on the theory of subtractive color of the three primary colors.
